IMPROVEMENT IN ICE-CREAM FREEZERS.

Specification for wing part of Letters Patent. No. 112.951, datedSeptember I6, 1873; application filed March 3, 1873.

To all whom it may concern:

Be it known that I, CHARLES E. SIMMONS, of Monroe, in the county ofGreene and State of Wisconsin, have invented certain new and usefulimprovements in lceCreani Freezers; and I do hereby declare that thefollowing is a full, clear, and exact description thereof, referencebeing had to the accompanyingdrawings and to the letters of referencemarked thereon, which form a partof this specific-a tion.

The nature of my invention consists in the construction andarrangement-of an '00- earn freezer, as will. be hereinafter more fullyset forth,

In order to enable others skilled in the art to which my inventionappertaius to make and use the some I will now proceed to de scribe itsconstruction and operation, refcc ring to the annexed drawing whichrepresents a central vertical section of my freezer.

A represents the tub for the ice and salt, having in the center of itsbottom a depression or socket for the insertion of the pivot a formed inthe center of the bottom of the cylinder 15. This cylinder forms thereceptacle for the cream, and is closed on 'top by a, cor rugated cover,U. 1) is a large cogn'hcel provided with crank E to turn thecreamheaters, said wheel, together with the vertical rod or shaft G andcylinder or tube II, being arranged in their respective positions in asuit able frame-work attached to the tub A. The vertical rod or shaft (lis at its top provided with a small cog-wheel or pinion, I), which gearswith the top of the cogwvheel .l); and within the croamcyliiuler B theinner or con tral heaters I I are attached to said rod or shaft, so thatby the turning of the cog-wheel l) the shaft and heaters are rapidlyrevolved. The shalt U passes through the cylinder H, which has a pinionor small cogwvheel, r], at the top, which gears with the bottom of thelarge cog-wheel l). 'ithin the cylinder B,

. near the top there f, the outside heaters J J are attached, or ratherconnected, to the lower end of the tube or cylinder 1i. Thus thecogwheel 1) turns the inside or central scrapers in one direction, andat the same time the'outside scrapers in the opposite direction. To thedisk which connects the outside heaters J J with the tube II areattached rods e 0, sun rounded by springs i i, and similar rods andsprings are also arranged on the annular dish connecting the lower endsof said heaters. Upon the outer ends of the rods 6 0 are placed."ertieal nooden scrapers K K, which impinge by the action ot the springs'2' 1? against the sides of the creanrcylindcr B.

()n turning the crank E the inside luiateir. 1' revolve rapidly in thecream, while the wood scrapers K K, pressed by the spiral springs 2against the in ide of the large cylinder ll, ho d it sufficiently ironto give it- {the whole cylinder) a reverse revolution. By pressure oi.in hand, however, on the top of the corruga ed cover 0 the cylinderbecomes stationary. while both heaters revolve in opposite illflltjiOlithe scrapers preventing any adhesion to the sides of the cylinder,thoroughly breaking and mixing the cream, preventing granulation, andfreezing it finely in the shortest possible time.

The corrugations in'the cover 1 are to regulate the movei'ncutof thecylinders, letting; them slide under the pressure of the-fingers, so asto permit the cylinder to revolve rapid y or slowly in the ice, asdesired, frerptently stopping it by increasing the pressure, so as toscrape the inside of the cylinder, then permitting it again to revolve.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

The combination of the cylinder B, coguhcel ll, piuions I) d, shaft G,tube H, heaters I J, and scraper K, all constructed and arranged tooperate substantially as and for the purposes herein set forth.

In testimony that I claim the foregoing as my own I atlix my signaturein presence of two witnesses.
